glutPopWindow,  glutPushWindow - change the stacking order
       of the current window relative to its siblings.

SYNTAX

       void glutPopWindow(void);
       void glutPushWindow(void);

DESCRIPTION

       glutPopWindow and glutPushWindow work  on  both  top-level
       windows  and subwindows. The effect of pushing and popping
       windows does not take place immediately. Instead the  push
       or  pop  is  saved  for  execution upon return to the GLUT
       event loop. Subsequent push or pop requests  on  a  window
       replace  the previously saved request for that window. The
       effect of pushing and popping top-level windows is subject
       to the window system's policy for restacking windows.
